[PATCH 0/6] Dynamic allocation of memory regions and IBM vTPM v2

Subject: [PATCH 0/6] Dynamic allocation of memory regions and IBM vTPM v2

This is an addition to the series sent from Daniel Axtens 

Patch 'ieee1275: request memory with ibm,client-architecture-support' 
implements vectors 1-4 of client-architecture-support negotiation
However, during some tests, we found this can be a problem if:

- we have more than 64 CPUs
- Hardware Management Console (HMC) is configured to minimum of CPUs >64 (for 
example, min of 200 CPUs)
- Grub needs to request memory.

If vector 5 is not implemented, Power Hypervisor will consider the default 
value for vector 5 and 64 will bet set as the maximum 
number of CPUs supported by the OS, causing the machine to fail to init.
Today we support 256 CPUs (max) on Power, so we need to implement vector 5 and 
set the MAX CPUs bits to this value.

The patches 11-15 aren't merged to the grub tree yet, so I'm sending those 
patches again together with my patch to implement vector 5
on top of them.

The patches 11-15 contains the following:

Daniel Axtens (4):
  ieee1275: request memory with ibm,client-architecture-support
  ieee1275: drop len -= 1 quirk in heap_init
  ieee1275: support runtime memory claiming
  [RFC] Add memtool module with memory allocation stress-test

Stefan Berger (1):
  ibmvtpm: Add support for trusted boot using a vTPM 2.0
